Allows you to create new objects based on geometric and data operations between two existing object groups. These operations are':' Intersect, Union, Erase, Identity, Clip, Paste and Symmetric Difference..

Overlay

The command ‘SPMOVERLAY’ in Spatial Manager™ for GstarCAD allows you to create new entities based on geometric and data operations between two existing entity groups.

This function allows you to generate new entities in the drawing by performing geometric operations between two groups of existing entities: “Source” (Group 1) and “Overlay” (Group 2).

• Entities selection: For Group 1 and Group 2, review the selection control.
• Overlay parameters and options:
  • Operation:
    • Intersect.
    • Union.
    • Erase.
    • Identity.
    • Clip.
    • Paste.
    • Symmetric Difference.
  • General options:
    • Table/Layer name: Defines the target Layer and data table name for the newly created entities.
      • Apply random colors to new Layers.
      • Fill areas using Hatches.
    • Treat closed polylines as polygons (Both Source and Overlay sets): When checked (default value), all closed polylines in the drawing will be considered polygons and not linear entities.
